The present disclosure relates to systems, methods, and computer-readable media for tracking smart devices in vehicles.

BACKGROUND

Autonomous vehicles can be used to transport users to desired destinations. Smart devices, for example smartphones and tablets have become more common and omnipresent than ever before. Users carry them throughout the day, and are regularly utilizing them for the variety of functions they are able to perform. For example, smart devices may be used to request a ride, such as via a taxi or ride service, that may include a human-operated or autonomous vehicle. It happens that during the ride the passenger is using the smart device, and then after completing the ride, the passenger accidently leaves the smart device in the vehicle. However, the passenger may not realize they left the smart device for some time, well after the vehicle has left the location where the passenger disembarked. Retrieval of a left smart device may be complicated, time consuming, and may not ultimately be successful.

FIG. 1 is an example process flow for a method 100 of providing warnings to users to retrieve smart devices left in vehicles, in accordance with one or more embodiments of the disclosure.

At block 152, a user 180 may engage transportation services using a vehicle 102. The vehicle 102 may include an autonomous vehicle, semi-autonomous vehicle, or any other type of vehicle. The user 180 may engage a transportation service by requesting a ride using an application installed on mobile device 110. The mobile device 110 may include a smartphone, a tablet, a laptop, a wearable device, or the like. In some embodiments, the application of the mobile device 110 may send the request for the ride to controller 105 associated with the vehicle 102. The controller 105 may be a computer-based device that controls any number of functions associated with the vehicle 102, including communications with third party devices, such as the mobile device 110. In other embodiments, the application of the mobile device 110 may send a request to a service operating on a server 125, and the service of the server 125 may send the request to the controller 105 of the vehicle 102. In response to receiving the request, the controller 105 may unlock doors of the vehicle 102, so that the user 180 may get inside the vehicle and begin the ride. The user 180 may use the application installed on the mobile device 110 to indicate a destination for a ride so that the vehicle 102 may determine a route.

The user 180 may be wearing or otherwise be operatively connected to a computer-based wearable device 115. The wearable device may include a smart watch, smart glasses, a fob, and the like. The wearable device 115 can be coupled with the mobile device 110 via a wireless communication using one or more of the mobile applications of the mobile device 110 and wearable device 115. Using the mobile applications, the mobile device 110 may request and receive information from the wearable device 115. The information may include movement data associated with movement detected by the wearable device 115 and/or the mobile device 110, such as speed, direction, acceleration, number of steps taken by the user 180, distance walked by the user 180, and the like. The wearable device 115 may collect and/or generate this information using one or more motion sensors, such as accelerometers and gyroscopes, as well as other sensors/systems such as positioning systems, cameras, and the like. The wearable device 115 and/or mobile device 110 may further include an application (e.g., software) to process raw motion data from the motion sensors to generate a number of steps, speed, distance, and the like.

Similarly, the mobile device 110 may include one or more motion sensors, such as accelerometers and gyroscopes, as well as other sensors/systems such as positioning systems, cameras, and the like. The mobile device 110 may include an application (e.g., software) to process the raw data from the motion sensors to generate a number of steps, speed, distance, and so forth. It should be noted that when the user 180 holds the mobile device 110 by a hand, in a pocket of clothing, or in a handbag, the movement data obtained with the motion sensors of the mobile device 110 and the movement data obtained with the motions sensors of the wearable device 115 may be substantially similar However, if user 180 leaves the mobile device 110 in the vehicle 102 and walks away, the movement data of the mobile device 110 may no longer match the movement data of the wearable device 115. For example, the motion data collected by the mobile device 110 and the motion data collected by the wearable device 115 may not match (e.g., may not be exact or may not be within a given threshold value of one another). Such may be an indication that one device is moving with the user 180 and the other has been left in the vehicle.

At block 154, the vehicle 102 may drive the user 180 to the destination, as specified in the request. Once the user 180 is in the vehicle, the controller 105 may synchronize with the mobile device 110 and/or the wearable device 115 using one or more pre-installed applications. The synchronization can be carried out using a wireless communication, such as WiFi™ direct, Bluetooth™, nearfield commination (NFC), and so forth. After synchronization completes, the controller 105 may exchange data with the mobile device 110 and/or wearable device 115. For example, the controller 105 may send, per request, data regarding speed of the vehicle 102, status of closing and opening doors of the vehicle 102 (e.g., as measured by vehicle sensors), current location, for example current global positioning system (GPS) coordinates of the vehicle 102 to the mobile device 110 and/or wearable device 115. The mobile device 110 or the wearable device 115 may send, per request from the controller 105 or the mobile device 110 or the wearable device 115, movement data and location data, for example, GPS coordinates associated with the mobile device 110. Similarly, the wearable device 115 may send, per request from the controller 105, movement data and location data, for example GPS coordinates associated with the wearable device 115.

At block 156 user may leave the vehicle 102 upon arrival at the destination. The controller 105 may then send to an application located on a server 125 in the computing cloud 120, via a wireless communication 130, a message indicating that the ride has ended and indicating that user 180 has left the vehicle. The user's departure may be indicated by the detection of a door being unlocked, a door opening, a seat pressure sensor detecting the removal of weight, etc., as may be determined by the controller 105. After the user 180 has the left the vehicle 102, the controller 105 may close and lock the doors of the vehicle 102. However, it may be possible that the user 180 has accidently left the mobile device 110 in the vehicle 102.

At block 158, it may be determined that the user 180 departed the vehicle 102 and left the mobile device 110 in the vehicle. The determination that the mobile device 110 is left in the vehicle 102 can be carried out using either the controller 105, the mobile device 110, the wearable device 115, and/or an application executing on the server 125.

According to some example embodiments, the wearable device 115 may receive, from the controller 105, an indication that the user 180 left the vehicle 102. For example, the controller 105 may send notification that vehicle 102 came to a complete stop, and a door of the vehicle was unlocked, opened, and then closed. The mobile device 110, upon receiving such indication, may request movement data from the wearable device 115. The mobile device 110 may compare the movement data (acceleration, speed, number of steps, or distance) from the wearable device 115 with the movement data obtained using sensors of the mobile device 110. For example, the mobile device 110 may compare number of steps recorded during a pre-determined time period, for example a pre-determined number of seconds past since receiving indication that the user 180 left the vehicle 102. If a movement (e.g., number of steps) detected by the mobile device 110 is not similar to that of the wearable device 115, for instance, within a threshold of each other, then it may be determined that the mobile device 110 was left in the vehicle 102. For instance, if the wearable device 115 provides the mobile device with an indication that four steps have been taken by the user but the mobile device 110 determines no steps have been taken, then it may be determined that the mobile device 110 was left in the vehicle 102. Similarly, if a walking distance recorded with the mobile device 110 is unchanged and a walking distance recorded with the wearable device 115 is changed then it is determined that the mobile device 110 is left in the vehicle 102 while the user 180 is walking away from the vehicle 102. The mobile device 110 may also compare GPS coordinates and acceleration data recorded with sensors associated with the mobile device 110 and sensors of the wearable device 115.

In some embodiments, the determination that the mobile device 110 is left in the vehicle can be carried out by the mobile device 110, as described above, or by the wearable device 115, the controller 105, or the server 125. For example, the retrieval and comparison of the movement may be performed by the mobile device 110, as described above, or by the wearable device 115, or by the server 125, and that device or another may initiate alerts and manage a device retrieval process.

For instance, in an embodiment, the wearable device 115 may receive an indication from the controller 105 that the user 180 left the vehicle. The wearable device 115 may further request the movement data and/or location data from the mobile device 110 recorded during a pre-determined time period since receiving the indication from the controller 105. The wearable device 115 may further compare the movement data and/or location data from the mobile device 110 and the compare the movement data and/or location data from the wearable device 115. If the movement data from the mobile device 110 does not match the motion data from the wearable device 115, for example, within a threshold, then it may determine that the user 180 left the mobile device 110 in the vehicle. The wearable device 115 may further send a message to the controller 105 indicating that the mobile device 110 was left in the vehicle 102. The message may also include a distance of the user 180 from the vehicle 102, for example, the number of steps the user walked away from the vehicle 102.

In some embodiments, the wearable device 115 or the mobile device 110 may request movement data and location data of vehicle 102 from the controller 105. The wearable device 115 may compare movement data and/or location data from the wearable device 115 with both movement data and/or location data from the wearable device 115 and movement data and/or location data of vehicle 102 from the controller 105. For example, if the wearable device 115 does not receive movement and location data from the mobile device 110 (or vice versa), or the wearable device 115 may supplement the movement and location data from the mobile device 110 (or vice versa), then the controller 105 may provide such data for analysis.

In some other embodiments, after determining that the user 180 left the vehicle 102, the controller 105 may request last movement data and/or location data from the mobile device 110 and the wearable device 115. The controller 105 may further compare changes in the movement data and/or location data from the mobile device 110 and the wearable device 115. If the changes in the movement data and/or location data from the mobile device 110 and the wearable device 115 differs, then the controller 105 may determine that the mobile device 110 was left in the vehicle 102. The controller 105 may also compare changes in movement data from the mobile device 110 and movement data of vehicle 102. The controller 105 may use motion data and/or location data from the wearable device 115 to estimate a distance that the user 180 walked away from the vehicle 102.

At block 160, the mobile device 110 may generate and send message to wearable device 115 and/or to the controller 105 indicating that the mobile device 110 was left in the vehicle 102. The messages may also indicate a distance that user 180 walked away from the vehicle 102. The messages may further include an amount of time given to the user 180 to retrieve the mobile device 110 from the vehicle 102.

Upon receiving the message indicating that the mobile device 110 was left in vehicle 102 or determining that the mobile device 110 was left in the vehicle 102, the wearable device 115 may be configured to alert the user 180 using a vibration and/or sound, or some other indication. If the wearable device 115 includes a graphical display system, the wearable device 115 may be configured to display a warning message and a timer showing amount of time (for example number minutes or seconds) given to the user 180 to return to the vehicle 102 and retrieve the mobile device 110. For example, it may take five seconds to determine that user 180 walks away from the vehicle 102 without the mobile device 110. The message to the wearable device 115 may include, for example, “You left your device in the vehicle and you will have fifteen seconds from now to go back and take it,” or something similar.

At block 162, upon receiving the message indicating that the wearable device 110 was left in vehicle 102 or determining that the wearable device 110 was left in the vehicle 102, the controller 105 may monitor movement data and location data received from the wearable device 115 to determine distance of the wearable device 115 (and hence, user 180) from the vehicle 102. The controller may unlock the doors of the vehicle 102 only when the coordinates wearable device 115 match substantially the coordinates of the vehicle 102 (e.g., when the wearable device 115 is within a threshold distance of the vehicle 102). In addition, the controller 105 may unlock the doors of the vehicle 102 only if the time allotted to the user 180 to retrieve the mobile device 110 has not expired. The time can be estimated based on distance between the vehicle 102 and the user 180. In some embodiments, the time to retrieve the mobile device 110 may be fixed at a pre-determined value. The controller 105 may also determine that user 180 going back to the vehicle 102 and the time allocated to user 180 to retrieve the mobile device 110 has almost expired. In this situation, the controller 105 may extend the time given to retrieve the mobile device 110 to give the user 180 one more chance to retrieve it.

In some embodiments, the steps 158-162 can be undertaken only if the charge of batteries of the wearable device 115 and the mobile device 110 are more than a threshold batter capacity (e.g., 15% of battery capacity).

In some embodiments, if the user 180 fails or forgets to retrieve the mobile device 110 from the vehicle 102, the controller 105 may send a message to the driving application at server 125 indicating that the user 180 left the mobile device in vehicle 102. The driving application may store the indication in a database. When a next user requests transportation service with the vehicle 102, the driving application may send the message to the next user indicating that user 180 left the mobile device 110 in vehicle 102. The message may also allow the next user to select from two options: 1) to leave the mobile device 110 inside the vehicle 102; or 2) take the mobile device 110 and return it to the user 180. In addition, the vehicle 102 may include one or more cameras to monitor interior of the vehicle 102 to prevent other users from taking the mobile device 110 undetected.

FIG. 3 is an example process flow 300 for a method of providing warnings to users to retrieve smart devices left in vehicles in accordance with one or more embodiments of the disclosure. The process flow 300 may be implemented using wearable device 115 and other devices of architecture 200 depicted in FIG. 2. For example, the steps of the process flow can be executed by one or more processor(s) of the mobile device 110 or one or more processor(s) of the controller 105.

At block 302 of the process flow 300, the one or more processor(s) may execute computer-executable instructions stored on memory to pair the mobile device 110 to a controller 105 of the vehicle 102. For example, the one or more processor(s) of the wearable device 110 may send a request for transportation service to computing cloud 120 or server 125. The one or more processor(s) of the computing cloud 120 or the server 125 may send the request to controller 105 of the vehicle 102. The request may include GPS coordinates of the mobile device 110, medium access control (MAC) or other address of the mobile device 110, user identification of the user 180 of the mobile device 110, and a destination. Upon receiving the request, the controller 105 may establish a wireless communication with the mobile device 110 using information indicated in the request. The controller 105 may unlock doors of the vehicle 102 to allow the user 180 to get into the vehicle to start a ride to the destination. During the ride, the controller 105 and the mobile device 110 may exchange data via the wireless communication. User may wear wearable device 115 paired with the mobile device 110 via wireless communication.

At block 304 of the process flow 300, one or more processor(s) may execute computer-executable instructions stored on memory to determine that the vehicle arrived at a destination. The one or more processor(s) may determine current GPS coordinates of the mobile device 110 using sensors of the mobile device 110 and compare the current GPS coordinates to the GPS coordinates of the destination. The one or more processor(s) may also receive an indication from the sensors of the vehicle 102 that the vehicle 102 came to a complete stop. Determining that the vehicle 102 has arrived may be based on a predetermined route (e.g., based on a user's input using the mobile device 110 to indicate an arrival destination), determining that the user has departed the vehicle 102 (e.g., based on door sensor data), or that the user has provided an input (e.g., via the mobile device 110) that the ride has ended.

At block 306 of the process flow 300, one or more processor(s) may execute computer-executable instructions stored on memory to determine that the wearable device 115 is no longer disposed in the vehicle 102 while the mobile device 110 is still disposed in the vehicle 102. The determination can be based on comparison of movement data and location provided by sensors of the wearable device 115 and movement data and location provided by sensors of the mobile device 110. If movement data associated with the mobile device 110 and with the wearable device 115 are not the same or within a threshold difference, then it may be determined that at least one of the mobile device 110 and the wearable device 115 departed the vehicle 102 while the other was left in the vehicle 102. For example, motion indicating that one of the devices has moved a particular amount (e.g., distance, steps, etc.) since the ride was indicated as having finished, but the other device's motion data indicates that the respective device may still be in the vehicle 102, then the discrepancy may indicate that a device was left in the vehicle 102. Example process flow depicting details of the block 304 is shown in FIG. 4.

At block 308 of the process flow 300, one or more processor(s) may execute computer-executable instructions stored on memory to send, based on the determination, at least one alert concerning the wearable device 115 or the mobile device 110. The alert may include a message or some other indication that the wearable device 115 or mobile device 110 was left in the vehicle 102 and time allocated to the user 180 to retrieve the mobile device 110 or the wearable device 115 from the vehicle 102. The alert may also prompt the user 180 to respond with an indication that the user 180 intends to retrieve the wearable device 115 or the mobile device 110 within the allocated time.

FIG. 4 is an example process flow 400 for a method of determining that the wearable device is left in a vehicle in accordance with one or more embodiments of the disclosure.

At block 402 of the process flow 400, the one or more processor(s) may execute computer-executable instructions stored on memory to send a request to a wearable device 115 or the mobile device 110 associated with the user 180 for detected movement associated with the wearable device 115 or the mobile device 110.

At block 404 of the process flow 400, the one or more processor(s) may execute computer-executable instructions stored on memory to receive a message indicating detected movement associated with the wearable device 115 or the mobile device 110. For example, the message may include an indication of a number of steps detected by the wearable device 115 or the mobile device 110 during a pre-determined time period after the vehicle 102 comes to a complete stop or after a door of the vehicle 102 was open and closed. The indication that the vehicle 102 comes to a complete stop or after a door of the vehicle 102 was open and closed can be determined based on information provided by one or more sensors of the vehicle 102 (e.g., that doors opened and closed), based on a user's input indicating that a ride has ended, or based on a determination that the vehicle 102 has reached a predetermined destination (e.g., based on a user input provided by the mobile device 110).

At block 406 of the process flow 400, the one or more processor(s) may execute computer-executable instructions stored on a memory to compare the movement data collected by multiple devices (e.g., the mobile device 110, the wearable device 115, and/or the controller 105). The movement data may indicate that one or more of the devices have been associated with movement since a ride ended, but that one of the devices may not be associated with the same or similar movement. For example, if the movement data associated with the mobile device 110 indicates that the mobile device 110 has not moved from the vehicle 102 after a ride has ended, but the movement data associated with the wearable device 115 indicates that the wearable device 115 has moved from the vehicle 102 since a ride ended, then such may indicate that the mobile device 110 has been left in the vehicle 102.

At block 408 of the process 400, the one or more processor(s) may execute computer-executable instructions stored on a memory to determine that the wearable device 115 or the mobile device 110 was left in the vehicle 102. In some embodiments, a change in GPS coordinates of the wearable device 115 and change in GPS coordinates of the wearable device 115 can be compared to determine that the wearable device 115 was left in the vehicle. In some embodiments, a detected change in distance or number of steps walked by the user with the wearable device 115 can be compared to a change in in distance or number of steps detected by the mobile device 110 to determine that the mobile device 110 was left in the vehicle 102 or vice versa.

FIG. 5 is an example process flow 500 for a method of detecting that smart devices were left in a vehicle and facilitating retrieval of the devices, in accordance with one or more embodiments of the disclosure. The process flow 500 may be implemented using wearable device 110 and other devices of architecture 200 depicted in FIG. 2. For example, the steps of the process flow 500 can be executed by one or more processor(s) of the mobile device 110, or one or more processor(s) of the controller 105. The process flow 500 may be a continuation of the process flow 400 shown in FIG. 5.

The indication may also include a time period allocated to the user 180 to retrieve the mobile device 110 or the wearable device 115 from the vehicle 102. The wearable device 115 or the mobile device 110 may alert the user 180 by one or more of the following: displaying or otherwise providing a message or other indication that the wearable device 115 or the mobile device 110 was left in the vehicle 102 and the time period to retrieve the mobile device.

At block 504 of the process flow 500, the one or more processor(s) may execute computer-executable instructions stored on memory to determine that the user 180 is within proximity of the vehicle 102 within the time period given to the passenger to return to the vehicle. The determination that user 180 is within the proximity of the vehicle 102 can be performed based on the GPS coordinates of the wearable device 115 or the mobile device 110, and GPS coordinates of the vehicle 102. The one or more processors may request the GPS coordinates of the wearable device 115 via a wireless communication after sending the indication that the mobile device 110 is left in vehicle 102. The one or more processors may further compare GPS coordinates of the wearable device 115 or the mobile device 110 and the GPS coordinates of the vehicle 102 to determine the distance between the wearable device 115 or the mobile device 110 and the vehicle 102.

At block 506 of the process flow 500, the one or more processor(s) may execute computer-executable instructions stored on memory to cause to extend the time period given to the user 180 to return to the vehicle 102. For example, if the user 180 is within a distance threshold of the vehicle 102 and the time period is nearing expiration (e.g., within a threshold time of the expiration of the time period), then the time period may be extended to allow the user 180 to retrieve the mobile device 110. The one or more processors may cause to send an indication of the time extension to the wearable device 110 or to another device to indicate to the passenger that the retrieval time has been extended. It should be noted, that doors of the vehicle may remain closed and locked until it is determined that the user 180 of the wearable device 115 reaches the vehicle 102.
